The soon-to-be mother of three told host Ellen DeGeneres that her 4-year-old daughter North had taken to calling the unborn child, “Baby Sister.”

“My daughter thinks she’s tricky,” Kardashian West said. “We had a baby shower over the weekend, and I thought, ‘You know, I really do want to have a baby shower because I want [North] to feel that something’s coming and for her to really understand it.’ ”

She continued, “So, people brought toys and gifts and [North] was opening them all up the next day,” Kardashian West explains. “And she goes, ‘Mom, since Baby Sister’s not here, I think I need all of her toys in my room and play with them and make sure they’re all okay for Baby Sister.’”

When DeGeneres asked if North was excited about having a sister, the KKW Beauty mogul said, “[She] is really excited about that,” and added that when she was pregnant with 1-year-old son Saint, the process “was a little trickier.”

As well as getting ready for a third baby, Kardashian West admitted that she and husband Kanye did not have a name set in stone.

“At the baby shower, I was like, ‘I just want everyone to write a name on a little tile and see if there is something that sticks,’” she said. “We’re freaking out, we have no name.”

Despite not having a name planned, the reality star said her daughter was keen on one particular name.

“She has a toy, a llama,” she said. “She named it Star West. She names everything Star West.”
